Birch-leaf spirea, also called white spirea or shiny-leaf spirea, is a low-growing, deciduous shrub native to western North America. Growing 2-4 feet tall, it produces small, birch-like leaves and flat clusters of white or pinkish flowers appearing in late spring to early summer.
This species is extremely cold-hardy to zones 2-8 and thrives in full sun to part shade with well-drained soil and moderate moisture. It spreads via stolons and self-seeding, making it useful for borders, massing, and erosion control. The plant is fast-growing and low-maintenance once established.
